Which is where we get to the technical part of what a capacitor is.
FORBES: My Nomination For Worst Law Of The Year: Dodd Frank On Conflict Minerals
Chemical electrodes of this sort can store a lot more energy than the static electricity of a capacitor.
But the whole process of ion movement and chemical reaction is slower than the movement of electrons in a capacitor.
Strictly speaking the composite behaves not like a battery but more like a capacitor, or rather a supercapacitor, says Dr Greenhalgh.
The expert said a degraded capacitor, a circuitry component used in various electrical appliances, was the likely cause of the fire.
The capacitor will power electrical components such as the air conditioning and stereo, which are normally powered by an alternator connected to the engine.

It has Burr-Brown 2 Channel low-noise Op Amp, ELNA Audio Grade Capacitor and a R-core linear power supply - doesn't mean that much too you?
By using a capacitor instead, Mazda saves weight and space and, unlike a battery, it can charge and discharge instantly without deteriorating during prolonged use.

The better the insulator, the more charge a capacitor can hold.
Using a conductive capacitor that is integrated as part of the pen, it connects to an electromagnetic field generated by an excitation coil in the digitizer.

Or if Doc Brown had strapped a flux capacitor to the back of a comfy chair in Back to the Future (1985) instead of that iconic DeLorean?
In the transmission segment, it offers pre-designed modular protection, control and automation solutions for transmission system assets such as transmission lines, bus-bars, large transformers and capacitor banks.
FORBES: GE Targets High-Growth Power Equipment Market with Packaged Solutions
Engineers had learned that a resistor, which restricts the flow of electrical current, is best made of certain materials and a capacitor, which stores electrical charge, of others.
The technology came out of funding from the Defense Advanced Research Projects Agency (DARPA) to develop a super capacitor to desalinate ocean water into drinking water for the troops.

But capacitor banks tend to be very large and hard to site near customers (who love to guzzle power but complain about new power lines or hardware in their neighbourhood).
The computer industry constantly strives to pack more, and therefore smaller, components on to each chip, but the smaller a capacitor gets, the harder it is to store enough charge on it.
Everyone who puts a tantalum capacitor into a piece of electronics has to be able to show that that tantalum did not come, by however roundabout a route, from this area of conflict minerals.

"Esha Khare, 18, of Saratoga, California has received the Intel Foundation Young Scientist Award for developing a fast-charging super-capacitor that fits inside a cell phone, charges the battery in under a minute, and holds it for long, " the paper adds.
As eardrum vibrations naturally create a usable voltage from brain signals, the prototype can build enough charge in a capacitor to drive a very low-power wireless transmitter that relays the electrochemical properties of the ear and potentially diagnoses balance or hearing problems.
ENGADGET: MIT ear-powered wireless sensor sustains its charge through sound
By storing excess electrical energy that is generated by the dynamo in a capacitor, and getting the spring to unwind only when the capacitor charge falls below a certain threshold, it has proved possible to extend the playing time of the second-generation radio to about an hour.
We're not exactly sure what makes these virus transistors so special, but apparently the transistors they've built out of the nano-coated strands, and sandwiched between two electrodes, are easy to switch between ON and OFF states, since they don't need to build up a charge at a lame-o capacitor before they can be switched.
